[Runtime Feature]: Camera simulation PostFX features

What is the context of the feature/improvement?

While making Silent Hill 3 Remix mod, I've got an idea for new Runtime PostFX features, Silent Hill 3 use some post drawcalls to create some camera simulation effects. So camera simulation features might be a additional layer of realistic look in some games.

Please describe the feature/improvement?

For example:

• Film grain simulation (like in some Video Editing apps we can simulate film grain and change types such as: grain size, digital or analog grain, monochrome or colorful);
• Lens Flare(with customazible textures look of Flares) (maybe feature to attach to one light source, like in Silent Hill 3, one lens flare on flashlight);
• Depth of Field (simulation of depth of field effect of real lenses, with customazible bokeh's, curves and petzval bokeh. With Remix Logic, for example we could program Depth of Filed effect for cutscenes);
• Shutter Speed simulation (basicly more motion blur and smudged like look with Long Shutter speed values);
• Lens Distortion (some lenses have distortions on edges, that effect create curvy and realistic look sometimes in scenes).
• Applying LUTs, and more complex color correction on post-process;

What would be your solution? (optional)

A lot of effects that I described here already can be done with ReShade, almost all of them don't need additional inputs(only z-buffer for Depth Of Field). Maybe collaborate with ReShade, or create own PostFX features for Camera Simulation.
Thank you

The issue proposes several camera PostFX effects, including film grain, lens flare, depth of field, shutter-speed blur, lens distortion, and LUT-based color correction. Start by reviewing the runtime's existing PostFX capabilities and ReShade integration; no files, tests, or entry points are named. Done would require narrowing this proposal to a defined effect and agreeing on its implementation scope.
